I have a great friend (online only) that I've known for years and last week he told me that he wants to change his sex. Now, I consider myself to be a pretty open person especially when it comes to sexuality. On a personal level, I'm bisexual and I have quite a few friends IRL and online that come from all different areas gay trans, etc, however this is the first time someone I know has changed like this 'before my eyes' if you will.... and, for some reason.. when he asks me to refer to him as 'she' I just.. cant. It kinda freaks me out, and my mind can't let it go that this person is male. Any comments or suggestions?
